Self-adaptive software evaluates its own behavior and changes its behavior when the evaluation indicates that the software does not accomplish what it is intended to do or when better functionality or better performance is possible. The self-adaptive approach in software engineering builds on well-known features like the use of errors and the handling of exceptions in languages like Lisp or Java and aims at improving the robustness of software systems by gradually adding new features of self-adaption and autonomity.This book originates from the First International Workshop on Self-Adaptive Software, IWSAS 2000, held in Oxford, UK in April 2000. The revised full papers presented in the volume together with an introductory survey by the volume editors assess the state of the art in this emerging new field and set the scene for future research and development work.

This book constitutes the refereed proceedings of the Fourth International Symposium on Theoretical Aspects of Computer Software, TACS 2001, held in Sendai, Japan, in October 2001.

Among the topics addressed are automata theory, concurrency, control-flow analysis, lambda calculi, model checking and program logic.

This volume provides the formal methods practitioner with a survey of the key software specification methods. Each technique is demonstrated using the same case study - an invoicing system - to enable the reader to compare and contrast easily. Among the techniques covered are: UML, Z, SAZ, B, JSD, OMT, VHDL, Estelle, SDL and LOTOS. Most specification courses tend to focus on 1 or 2 key techniques and to have a theoretical bias; this book provides a basic overview of the main methods, and has a practical focus that allows the reader to apply their knowledge to real-life situations. It will prove essential reading for all industrial and commercial practitioners who need to expand their knowledge of software specification methods.

A presentation of what Maple can do and how it does it in the context of environmental sciences. The text includes introductory tutorials in each chapter combined with extensive marginal comments which are followed by a complete application. These include the contouring of water table data, the physical chemistry of kidney stones, and acid rain. The book also provides a special application to enable students to use "self help" in the case that Maple seem unable to do the simplest things.

This practical 'how-to'book describes all the key operations of ARIS Toolset - the market leading Business Process Modelling Tool. Using lots of screen shots and plenty of practical examples, Rob Davis shows how ARIS can be used to model 'your' business processes.Based on his experience of using ARIS in British Telecommunications plc, the author describes practical ways of using ARIS Toolset:- Explaining the models and techniques that will enable new users to start modelling quickly and effectively.- Introducing tips and short cuts which make using the tool much easier.- Giving insights into the ARIS concepts.- Explaining the rationale behind alternative ways of using the tool, their benefits and the trade-offs involved.- Tackling issues found in real projects (e.g. complex model structures, handling variety, etc), as opposed to the simple examples given in many books.In addition to describing how to use the tool, Rob Davis discusses how to create standards for using ARIS as well as giving guidance on how to use ARIS for process capture and design.Business Process Modelling with ARIS is a 'must have'for every user of ARIS.

Digital transformation is not about technology--it's about change. In the rapidly changing digital economy, you can't succeed by merely tweaking management practices that led to past success. And yet, while many leaders and managers recognize the threat from digital--and the potential opportunity--they lack a common language and compelling framework to help them assess it and guide them in responding. They don't know how to think about their digital business model. In this concise, practical book, MIT digital research leaders Peter Weill and Stephanie Woerner provide a powerful yet straightforward framework that has been field-tested globally with dozens of senior management teams. Based on years of study at the MIT Center for Information Systems Research (CISR), the authors find that digitization is moving companies' business models on two dimensions: from value chains to digital ecosystems, and from a fuzzy understanding of the needs of end customers to a sharper one. Looking at these dimensions in combination results in four distinct business models, each with different capabilities. The book then sets out six driving questions, in separate chapters, that help managers and executives clarify where they are currently in an increasingly digital business landscape and highlight what's needed to move toward a higher-value digital business model. Filled with straightforward self-assessments, motivating examples, and sharp financial analyses of where profits are made, this smart book will help you tackle the threats, leverage the opportunities, and create winning digital strategies.

Many antiquated or legacy systems are still in operation today because they are critical to the organizations continued operations or are prohibitively expensive to replace. This book guides practitioners in managing the process of legacy system evolution. The author introduces a comprehensive method for managing a software evolution project, from its conception to the deployment of the resulting system. The book helps managers answer two critical decisions: What is the best way to evolve a particular legacy system? and How can the legacy system be migrated to a selected target architecture?

lfimplementing systematic reuse is risky, not doing it is even more risky. Trying systematic reuse unsuccessfully can cost precious time and resources and may make management sceptical of trying it again. But if your competitors do it successfully and you do not, you may lose market share and possibly an entire market. W. B. Frakes and S. Isoda, 1994 Software companies today are faced with new and more challenging market pressures. In response to this challenge, they have to reduce the time-to-market with new or enhanced products, increase the diversity of products available to the customers, and enhance the standardisation and interoperability of the products. At the same time, many companies carry the burden of large legacy systems, that have become too expensive to maintain and cannot sustain the demands of the marketing department for alterations, leading to business opportunities being lost [BEN95]. However the systems are very valuable and cannot be simply replaced because of the costs that such an operation entails. Simply replacing them may be too expensive because of the huge volumes of on-line data that must be converted, among other reasons.

Es war mir eine grosse Freude, zusammen mit meinem Freund Colin Hood dieses Buch zu schreiben. Seine reichhaltigen Erfahrungen aus sehr vielen unterschiedlichen Industriezweigen, auf unterschied- chen Ebenen und in verschiedenen Entwicklungsabteilungen geben tiefe Einblicke in die unterschiedlichsten Unternehmenskulturen. Um das oft als sehr trocken angesehene Thema des Requirements Management und Engineerings spannend zu gestalten, haben wir Teile dieser Erfahrung an Hand von Stories von Colin Hood in die einzelnen Kapitel des Buches eingestreut. Diese Stories sind gr- tenteils authentisch, manchmal auch aus mehreren Gegebenheiten konstruiert. Der Begriff Requirements Management begleitet mein Berufs- ben nun seit 1991. Damals, als Informatiker der bereits einige Erf- rung in der Softwareentwicklung und Durchfuhrung von Softwa- projekten sammeln konnte, war mir bereits bei der ersten Beschaf- gung mit diesem Thema klar, dass hier einiges an Potential brach liegt. In dieser Zeit Information uber Requirements Management und Engineering zu bekommen, war nicht ganz einfach; Bucher daruber gab es kaum. Bei Organisationen wie IEE, IEEE und NCSE (aus der dann spater die INCOSE entstand) beschaftigten sich aber bereits Arbeitsgruppen mit Requirements Management oder mit Requirements Engineering (wir machen uns im Verlauf des Buches noch Gedanken zu diesen und ahnlichen Begriffen)."

Serviceorientierte Architektur, kurz SOA, das Zauberwort in modernen Unternehmen: Durch SOA hoffen Manager, dass Firmen flexibler, agiler, einfach schneller und unmittelbar auf Kundenwunsche eingehen konnen. Der Autor zeigt v.a. die Auswirkungen der Serviceorientierung auf Softwareentwicklung, Organisation und Prozesse. Denn die Einfuhrung einer SOA hat massive Auswirkungen auf alle Teile eines Unternehmens und seine Wertschopfungskette. Mittelfristig erfordert sie neue Kooperations- und Kommunikationsformen. Plus: die Grenzen von Services aus systemtheoretischer Sicht sowie mogliche Losungen fur sehr grosse Systeme und mobile Anwendungen."

Science demands that all theory must be checked by experiment. Richard Feyn man, Nobel Laureate in physics (1965), reminds us in a wonderful quote that "The test of all knowledge is experiment. Experiment is the sole judge of sci entific truth. " 1 It is because nonlinear physics can be so profoundly counter intuitive that these laboratory investigations are so important. This manual is designed to be used with the text Nonlinear Physics with Maple for Scientists and Engineers. Understanding is enhanced when experiments are used to check so please attempt as many of the activities as you can. As you perform theory, these activities, we hope that you will be amazed and startled by strange behav ior, intrigued and terrorized by new ideas, and be able to amaze your friends as you relate your strange sightings Remember that imagination is just as impor tant as knowledge, so exercise yours whenever possible. But please be careful, as nonlinear activities can be addicting, can provide fond memories, and can awaken an interest that lasts a lifetime. Although it has been said that a rose by any other name is still a rose, (with apologies to Shakespeare) the authors of this laboratory manual have, in an endeavor to encourage the use of these nonlinear investigations, called them experimental activities rather than experiments. A number of design innovations have been introduced: A."

OpenStep is a landmark development. It brings together many of the features software developers have been seeking in a software development environment: true object orientation, open systems architecture, interoperability, robust class libraries, and the ability to separate the user interface from business logic in a way that allows applications to be deployed on multiple platforms, and over the World Wide Web. This book is an in-depth introduction to OpenStep and its use in developing business applications. The authors are experienced OpenStep developers and bring to the book the understanding that the process of object-oriented development is just as important as understanding the technology of object-oriented development. As a result, every potential OpenStep developer will find much of interest in this book.

The Maple ODE Lab Book is intended to provide a thorough introduc tion to using symbolic computation software to model, solve, explore, and visualize ordinary differential equations. It is best used as a supplement to existing texts (see the bibliography for some of our recommended texts). Maple was chosen as our software package because of its ease-of-use, affordability, and popularity at many universities and colleges around the world. The version being used is Maple V Release 4. If you have a previous release of Maple, some of the commands shown in this lab book will work differently (or not at all), but the basic groundwork for solving ODEs hasn't changed. Speak to your system administrator about upgrading to Release 4, or contact: Waterloo Maple Inc. 450 Phillip Street Waterloo, Ontario CANADA N2L 5J2 Phone: (519) 747-2373 FAX: (519) 747-5284 E-mail: [email protected] WWW: http: //www.maplesoft.com 1 2 Chapter 1. Introduction How This Lab Book Is Organized Each subsequent chapter of this lab book contains information and ex amples of how to apply Maple to various elements of ordinary differential equations. It is suggested that you read the chapters with your computer on and Maple V Release 4 running. You can then execute many of the com mands yourself and experiment by changing various parameters and/or initial conditions, observing the corresponding changes in the results."

The Maple Summer Workshop and Symposium, MSWS '94, reflects the growing commu nity of Maple users around the world. This volume contains the contributed papers. A careful inspection of author affiliations will reveal that they come from North America, Europe, and Australia. In fact, fifteen come from the United States, two from Canada, one from Australia, and nine come from Europe. Of European papers, two are from Ger many, two are from the Netherlands, two are from Spain, and one each is from Switzerland, Denmark, and the United Kingdom. More important than the geographical diversity is the intellectual range of the contributions. We begin to see in this collection of works papers in which Maple is used in an increasingly flexible way. For example, there is an application in computer science that uses Maple as a tool to create a new utility. There is an application in abstract algebra where Maple has been used to create new functionalities for computing in a rational function field. There are applications to geometrical optics, digital signal processing, and experimental design."

The advent of relatively inexpensive but powerful computers is af fecting practically all aspects of our lives, but some of the greatest influence is being felt in the physical sciences. However, university curricula and teaching methods have responded somewhat cautiously, having only recently come to terms with the now omnipresent calcula tor. While many instructors at first feared that the widespread use of pocket calculators would lead to generations of students who could not multiply or perhaps even add, few now seriously lament the disappear ance of slide rules, logarithm tables, and the often error-bound tedium that such tools of the trade demand. Time that used to be spent on the use of logarithm tables and manual square-root extraction can be prof itably turned to earlier studies of calculus or computer programming. Now that the calculator has been accepted into the classroom, we face a computer-software revolution which promises to be considerably more profound. Modern textbooks in the physical sciences routinely assume their readers have access not only to calculators, but often to home or even mainframe computers as well, and the problems teachers discuss and assign students can be more complex and often more realistic than in the days of only pad and pencil computations. As less effort is spent on numerical computation, more can be devoted to conceptual under standing and to applications of the increasingly sophisticated mathe matical methods needed for a real appreciation of recent advances in the discipline."

In practical management, a policy maker often has to make a choice from among various alternatives. Quite often, there are several conflicting criteria to take into account. In addition, some criteria are non-numeric: they can only be expressed as `more' or `less'. The QUALIFLEX method for multicriteria analysis has been developed by the Netherlands Economic Institute to handle such problems. It is designed for use at all levels of decision making, both in the public and private sector. QUALIFLEX has the following features: simultaneous use of qualitative and quantitative data; full flexibility with regard to alternatives and criteria; scores in their own, natural measures; different weighting options for the criteria; sensitivity analysis of the relative weights of the criteria; the result is an optimal ranking of the alternatives. GBP/LISTGBP The Decision Support System QUALIFLEX 2.3 is a fully revised version of the program Micro-Qualiflex. The main improvements are: now user friendly and menu driven; graphical presentation; reversibility and data editing; optional input from (dBase) files.
